Guys (and gals)
If you get severe backfire right when you let off the gas (with exhaust air
injected vehicles), check the vacuum operated diverter valve. The diverter
valve controls the air flow to the air rail entering the exhaust manifold.
If it malfunctions, you'll get a nasty backfire when you let off the gas.
Sometimes even between shifts if your really stepping on the accelerator.
